    摘要： In order to prevent the recording performance from degradation in radio frequency recording, there are provided a film magnetic head and a recording reproducing sectional pattern magnetic head which has magnetic pole width less than 2 µm and a ultra high density magnetic storage apparatus of 10 Gb/in 2 grade. In the recording head, a lower part magnetic film serves as a shielding film of a reproducing department. A gap film of a non-magnetism is formed during the formation of the upper and lower part magnetic films. One part of the lower or upper part magnetic film has a resistivity higher by more than 80 µΩcm than other parts. The upper part magnetic film is formed by a flame galvanising. A gap department of the lower or upper part magnetic film is shaped convex.
